To all whom it may concern:

Be it known that I, FRANCIS 0. BROWN, a

. citizen of the United States, and resident of New Bri hton, StatenIsland, borough and county 0 Richmond, city, and State of New York, haveinvented certain new and useful Im rovements in Fountain-Pens, of whichthe following is a specification.

My invention relates to fountain ens and particularly to that t pe inwhic a nibcarrying feed-bar is a apted to be projected from the barrelor retracted into the same.

The object of my present invention is to prevent the spatterlng of inkat the moment when the pen is in use or when withdrawin it therefrom,and to properly position and steady the nib in the writing osition.

Reference is to be had to t e accompanying drawing in which Figure 1 isa longitudinal section of a fountain pen showing the nib in position foruse; ig. 2 is a cross section on line 2-2 of Fig. 1; Fig. 3 illustratesanother form of pen with my present invention applied thereto; and Fig.4 is a partial view of the same pen in the closed position.

In Figs. 1 and 2 the barrel A is rovided with a nozzle A havin a screw-tread A to receive the cap B an an internal incline or shoulder A", thepurpose of which will be fully explained hereinafter. The feedbar C issuitably guided in a packing D located at the rear end of the barrel andthe front end of this feed-bar carries the tongues C,.C between whichthe nib E is adapted to be received. In this form of the pen the nib isprojected and retracted by the action of a pin B located within the capB and ada ted to engage either the rear end .of the fee bar C when thecap is placed on the rear end of the barrel, or a recess or abutment Cprovided at the forward end of the feed bar.

The features described so far have been disclosed in prior-patents ofmine. According to my fpresent invention I place at the rear end 0 thetongues 0', C that is adjacent to the abutment G a ring or collar F, thediameter of which is greater than the internal diameter of the nozzle A,but of internal diameter adapted to engage the shoulder A when the penis in the writing position. The rlng might be placed loosely around the"fee tongues C, C but I prefer to hold it in earlier constructions.

'end of the ca place securely by fitting it into a curved slit at theforward end of the feed bar and the rear edge of the ring may be beveledto facilitate its insertion. In any event, however, the rin F surroundsboth feed tongues and is coated eccentrically with reference to the axisof the feed bar, or rather to'the pen eccentric arran ement is asfollows: As will be seen from ig. 1, the lower tongue C is bent sharplyand has a tendency to throw the feed bar to one side as the nib carryingportion passes through the nozzle A. The

eccentric location of the ring F counteracts this tendency and insures aproper position of the pen when projected. It will be seen that the ringF engages the inclined shoulder A along its entire periphery and thering therefore forms a perfect seal or valve closing communicationbetween the ink reservoir and the outside except forthe slight seat. Thereason for this feed channel which is left on'the upper face of the nibat each side C As the ring becomes seated and unseated uniformly on andfrom the entire circumferences of the inclined shoulder A" I avoid thespattering of ink which has been jectionable feature of some Thediameter of the ring is practically the same as that of the forwardportion of the feed bar.

found an 0 While in Figs. 1 and 2 the pen is advanced and retracted bythe pushing action of the cap,.-1n Fig. 3 I have shownmy inventionapplied to a pen in which the advance and of the upper tongue withdrawalof the nib are effected by turn ing a spirally grooved sleeve G which islocated at the rear end of the barrel and receives the feed bar Ctogether with a pin (1* projected from the feed bar through the spiralslot of the sleeve into a longitudinal slot A of the barrel. In theparticular construction shown the sleeve is. ada ted to be turned bymeans of a button secured thereto and provided with an axial recess Grto receive a pin B projected from the closed B at the outside thereof.

The purposeo this pin or lug B is to temporarily connect the cap withthe button so as to prevent loss of the cap, but it is not intended thatthe ca should beused as a means for turning the button G. The ring .Fwould be the same in this construction as in the one described above.This ring,- does since the inner surface-of the ring is spaced not exertany binding action on the-nib E i inclined internal shoulder at innersurface engages the tongue C in the construction shown.

It is not necessary,

however, gagement and the ring might surround the ton ues C, C loosely.The avoidance of a bin ing action on the nib is an advantage ofconsiderable importance in as much as it allows the nib to be removedreadily when desired, with the pen in the writing position.

-I claim as my invention:v

1. In a fountain pen,the the barrel having a reduced combination ofnozzle and an the inner end of the nozzle, a nib-carrying feed barmovable lengthwise in the barrel and provided at its forward end withtongues adapted to receive the nib between them, and with a .collararranged to engage the said inclined shoulder along its entirecircumference, and gneans for advancing and retracting the feed 2.
